Turkish police on Tuesday shut Istanbul's Bosphorus Bridge, a key transport link spanning Asia and Europe, to traffic and were searching a suspicious vehicle, broadcasters CNN Turk and NTV reported. Live footage of the bridge showed a series of white vehicles parked behind another lone white sedan near the European exit. Bomb disposal experts were near the vehicle, CNN Turk reported. Turkey is on edge after a suicide car bomb attack in the capital Ankara killed 37 people on Sunday. http://english.ahram.org.eg/News/191033.aspx
